BTOB’s Yook Sungjae wowed the crowd with the singing skills when he masked his identity as Mr. Bee.

On the episode of MBC’s “King of Mask Singer” aired on May 10, the third champion singer is chosen through an intense semi-final and final competition.

In order to choose the opponent for finalist Gold Lacquer, Mr. Bee and Sky Lark compete against each other in the semi final. Mr. Bee sings “Gratitude,” while Sky Lark sings “I Will Show You.”

Mr. Bee is forced to reveal his identity after losing the competition. Surprisingly, he is unmasked to be Yook Sungjae, bringing all the judges to a shock.

Towards the judges, he says, “I’m the least talented out of BTOB. I’ve been trying to follow the other older members since I was young. I wanted to show everyone what the youngster is truly capable of.”
